The names of Nat Hentoff and Albert J. McCarthy have become almost synonymous with jazz writing. Hentoff, editor of Jazz Review, writer for Downbeat, High Fidelity, New Yorker, and the Village Voice, and McCarthy, editor of Jazz Monthly, have raised jazz beyond mere appreciation and discography to a subject which demands the rigorous application of musicological, sociological, and historical analysis. In addition to their own contributions, the twelve articles they have commissioned by internationally noted critics and scholars provide almost revolutionary evidence of the emergence of Jazz as a serious art form.
